Setting breakpoints is failing using this test program and
vscode-mono-debugv0.16.2 and a non-vscode client vimspectorThe failure response is:
To break down the flow:

First, we receive a duplicate response to the
initializerequest:This is bad, but the client just ignores it, so whatever.
We then get a runInTerminal request:
2020-11-16 21:20:28,296 - DEBUG - Message received: {'command': 'runInTerminal', 'arguments': {'kind': 'integrated', 'title': 'Node Debug Console', 'cwd': '/Users/ben/.vim/bundle/vimspector/support/test/csharp', 'args': ['mono', '--debug', '--debugger-agent=transport=dt_socket,server=y,address=127.0.0.1:57681', 'Program.exe'], 'env': None}, 'seq': 3, 'type': 'request'}And send a response
2020-11-16 21:20:28,309 - DEBUG - Sending Message: {"seq": 4, "type": "response", "request_seq": 3, "command": "runInTerminal", "body": {"processId": 74070}, "success": true}That's all fine, and we get a response to the
launchrequest:2020-11-16 21:20:28,310 - DEBUG - Message received: {'success': True, 'message': None, 'request_seq': 1, 'command': 'launch', 'body': None, 'seq': 4, 'type': 'response'}But then we get rejections for the breakpoints request from earlier:
2020-11-16 21:20:28,332 - DEBUG - Message received: {'success': False, 'message': "error while processing request 'setBreakpoints' (exception: Cannot perform runtime binding on a null reference)", 'request_seq': 2, 'command': 'setBreakpoints', 'body': {'error': {'id': 1104, 'format': "error while processing request '{_request}' (exception: {_exception})", 'variables': {'_request': 'setBreakpoints', '_exception': 'Cannot perform runtime binding on a null reference'}, 'showUser': True, 'sendTelemetry': False}}, 'seq': 5, 'type': 'response'}But then we get a duplicate of that message:
And finally the exception breakpoints request is accepted:
2020-11-16 21:20:28,336 - DEBUG - Message received: {'success': True, 'message': None, 'request_seq': 3, 'command': 'setExceptionBreakpoints', 'body': None, 'seq': 6, 'type': 'response'}Subsequently there are other problems like duplicate responses to the
threadsrequest and such, but the inability to set breakpoints seems the most severe.Full log including DAP trace:
